We present an analysis of new and old high frequency VLBI data collected during the last 10 years at 5--22 GHz. For the jet components in the mas-VLBI jet, two component identifications are possible. One of them with quasi-stationary components oscillating about their mean positions. Another identification scheme, which formally gives the better expansion fit, yields motion with ∼ 9 c for H0=65 km s-1 Mpc-1 and q0=0.5. This model would be in better agreement with the observed rapid IDV and the expected high Lorentz-factor, deduced from IDV.
